What's the best radix pulley size that it's best considering iats/ timing ? Thanks in advance

 

How much boost do you want to produce?
Is the bottom end stock?
What size is the engine?

 

What's your setup? Mainly, displacement and exhaust setup. I'm running a 3.0" with catless LPP's and don't have any problems with IAT's, but also have the much larger Magnacharger CTS-V heat exchanger. I am at the end of the stock MAF's range too, so if I went with any more boost, I would have to go to a speed density tune.

 

I have 05 gmc Sierra vho 6.0 with , pacesetters headers, 3 inch dual exhaust no cats, radix mp112 with 2.8 , 60 lb inj. 90mm ls7 tb,flt level 6 trans with 2800 stall. I was just wondering if the heat from 2.8 pulley hurts more than it helps. Iats are 30-35 higher than ambient I'm in south Florida. I'm looking into getting larger hex , what's your dimensions on yours and where did you get it? Trying to get setup as good as I can I'd like to throw a decent cam in. Thanks guys. With current mods I'm at 450 hp and 485 tq

 

Keep that pulley, put in a good blower cam and you'll really have a fun fast ride.

Meth might be your next mod/friend due to the hot/humid enviroment you live in.

A NNBS hex would help also with a mix of distilled water and waterwetter, this is a proven 10* drop in IAT's.

 

Dimensions are twice as tall as the stock maggie truck h/e, same thickness and width. I think my IAT's cruising are about 20 over ambient, and 40 over after a 5-7 second WOT run (114 when it was 75 outside after a 7 second run).

 

That looks real clean , you get it from Magnuson ?

 

I did, but Frozen Boost has some good ones too (for a lot less). Didn't know that at the time. The one I have requires some trimming of the back side of the grill and a fabbed lower support bracket. Tootall and I made it out of aluminum square stock from Home Depot, it was pretty easy.

 

Anyone use the Lep blower cam ? Can't decide on cam. Would like an all around cam I occasionally tow a 7000 lb boat so I would like down low grunt.

 

Bump...
